Weighing Scales and Balances
Bench, platform and precision weighing instruments used to measure meat, ingredients, cure, packaging and process losses.
Meat blocks, trays, spices and curing salts differ greatly in mass and required tolerance. One scale rarely provides the best capacity and resolution for every task.
Maximum capacity states the largest load, while readability states the displayed increment. Neither alone proves accuracy or suitable uncertainty at a small dose.
Level, vibration, drafts, temperature, unstable benches and off-centre loading can affect the result. Scales should be placed and used within their design conditions.
Tare removes the container indication but does not remove capacity limits or uncertainty. Containers, scoops and staged additions should be controlled to prevent transcription or double-tare errors.
Use suitable traceable weights across the working range, including the doses that matter. Zero, repeatability and corner-loading checks can identify problems between formal calibrations.
Identify the scale, unit, result and ingredient, and define action for a failed check. Small cure doses may require a dedicated precision balance or a validated premix method.
